Lithotype - an overview ScienceDirect Topics

Lithotype in coal is a concept that distinguishes various bands in coal originally designed for “macroscopic” identification (Stach et al. 1982). The macroscopic identification of lithotypes was designed to be preliminary to petrographic examination whereby coal bands can be visually examined with the naked eye, especially in

Ambient‐Noise‐Spectrum Levels as a Function of Water

2005-8-3  Recent measurements have indicated that the level of ambient sea noise is a function of water depth. The results presented in this paper were obtained from measurements made simultaneously with four hydrophones located in the open ocean, on the slope of a sea mount, in an area of the Northwest Atlantic. The four hydrophones were located in water depths of 400, 1100, 2400, and 2500 fathoms (f).
